The automatic update to Safari 15 (Catalina) came across yesterday and now a huge number of websites no longer open. The problem seems to begin after attempting to login - the redirect confuses the browser. Does anyone know what's going on?
Switching to Opera and Brave until this gets fixed. See screenshot for typical error page below.....

This is an update to my original post and referencing your problems. Like you I suspected it was not just Safari 15. So.....
I reinstalled my Hard Drive -using the Restore feature - from my Time Machine Back-up of a few days before, i.e. before downloading the Security Patch and Safari 15.0 at the same time on Sept 21. which then caused all these problems.
The re-install took about 3 hrs. but it sorted everything out, and no issues. NOW the good part...
I decided to move step by step to update, to be current.
So I only allowed Apple to download and install the Security Patch, on its own. Once installed I checked everything was OK. And everything worked OK as before, but I am still using Safari 14.1.2
So, then and only then I downloaded and installed, ( as separate instruction) Safari 15.0 and nothing else. This item just took less than 5 mins. and my system didn't need to re-boot.
Again I tested everything and everything worked... no issues.... all websites opening their log-in pages.
My only thought is that installing the Security Patch and Safari 15.0 simultaneously caused the bug on my MacBook pro to prevent accessing -in my case - a whole host of financial institution log-in pages. However by downloading these 2 items separately allowed my system to update with no errors or issues.
Solved the problem. Simple reinstall
This fixed the same issue for me. Thanks for posting!!
I've done the same so I can use Ebay.
It's disappointing this has being going on so long without Apple doing something.
Safari 15 not opening websites - "a problem repeatedly occurred"
